On de Sitter Vacua in Type IIA Orientifold Compactifications
Frank Saueressig, Ulrich Theis, Stefan Vandoren
This letter discusses the orientifold projection of the quantum corrections to type IIA strings compactified on rigid Calabi-Yau threefolds. It is shown that N=2 membrane instanton…

Membrane Instantons and de Sitter Vacua
Marijn Davidse, Frank Saueressig, Ulrich Theis +1
We investigate membrane instanton effects in type IIA strings compactified on rigid Calabi-Yau manifolds. These effects contribute to the low-energy effective action of the univers…

Space-time foam in 2D and the sum over topologies
R. Loll, W. Westra
It is well-known that the sum over topologies in quantum gravity is ill-defined, due to a super-exponential growth of the number of geometries as a function of the space-time volum…
